我一直在上傳CSV文件到Heroku並進行處理時出現問題。它在我的本地環境中工作正常。只需要清楚,我不需要將文件保存在Heroku上,只需在請求期間訪問它,以便將其轉換爲字符串進行處理並導入到數據庫中。Heroku文件上傳問題
我想要做的是:
- 上傳CSV文件
- 地帶出了頭塊,根據該報告是
- 的網絡閱讀CSV數據到數據庫。這一步工作正常。
控制器代碼:
def create
@account = Account.find(params[:report][:account_id])
@file = params[:report][:file].read
# logger.info file.inspect
case @account.provider
when "Microsoft AdCenter" then @file.gsub!(/\A(.*)\n\n/im, "")
when "Google AdWords" then @file.gsub!(/\A(.*)\n/i, "")
else
raise "Invalid PPC report format"
end
end
這裏的堆棧跟蹤:

任何人都知道爲什麼它本地工作得很好,但隨後產生在Heroku上的錯誤?
謝謝!
